Lunar samples returned by U.S.S.R.'s Luna XVI (launched Sept. 12) contained less titanium and zirconium oxide and more ferric oxide than Apollo 11 samples, Soviet Academy of Sciences Vice President Aleksander Vinogradov was quoted as saying. Luna and Apollo samples "have an equally high content of space originated inert gases" but in overall composition the Luna XVI samples more closely resembled those from Apollo 12. Luna XVI material was fragmented basaltic type containing 70 chemical elements; granularity of soil increased with depth. Spherical, glazed formations of congealed droplets similar to those found by Apollo crews were present. Specific heat of lunar soil .did not depend on density, Vinogradov said, and, "on the average, corresponds to terrestrial rocks, while heat conductivity is characterized by extremely low values, considerably below those of the best heat-insulating materials on Earth.... It may be assumed that the general course of differentiation of the substance of the Earth and of the Moon and probably of other planets of the terrestrial type proceeded by similar routes, although reached different stages of development."

Supercritical wing developed by Dr. Richard T. Whitcomb, Jr., head of 8-Foot Tunnels Branch at LaRC, to increase speeds of U.S. transport aircraft by more than 160 km per hr (100 mph) without causing sonic booms was delivered to FRC for testing. Wing, which would be flown on modified F-8 jet fighter aircraft in spring 1971, was built by NR Los Angeles Div. at $1.8-million cost. (Miles, LA Times, 11/2/70)
Chemist Dr. Gustaf O. S. Arrhenius of Univ. of California at San Diego said in interview that he was working with NASA on plans to expand U.S. space program by sending unmanned spacecraft on "mission to an asteroid." He said idea had been presented to NASA in 1969 by Dr. Hannes O. Alfven, 1970 Nobel Prize winner in physics. (UPI, NYT, 11/4/70)
U.S. and U.S.S.R. resumed SALT in Helsinki after adjournment of nearly three months. (Gwertzman, NYT, 11 /4/70, 11)
